i just bought my buddies setup, it was dyno tuned in dallas, the results was 617hp w/ c16 gas.
mods
streetport w/ 3mm seals built by rotary performance
stock secondary injectors for the primary
1600cc secondary injectors
greddy 3 row fmic w/ greddy piping
hks twin power
power fc ecu
custom intake when driving on pump gas, off when driving w/ c16
triple ball bearing 74mm turbo ceramic coated built by i.t.s turbo now comp turbo
re amieya or however u spell it full exhaust
aftermarket radiator
dual denso fuel pumps
im sure theres more im just forgeting. would it b safe to turn up the boost on it, how much power do u think this setup is capable, also he didnt sell the fuel pump setup, would dual stock tt supra pumps workwhat kind of setup am i dealing w/? ive been in the car befor we pulled the engine and its a beast but is it capable for more power?
also he didnt sell me the turbo but i ordered the same one from comp turbo, i bought this setup for 4500 is that a good deal? thanks for yalls time

 

What does it make on pump gas? No offense, but it's my opinion that numbers recorded on race gas are kinda superficial unless you run race gas 24/7. Besides that, 600whp is NOTHING to sniff at! That's more power than you really ever need, or can even use.

 

honestly i dont know, there was a video of the dyno tune on speedfactorytuning.com and have a video of him smashing on a 600hp cobra on youtube its under shannons rx7

 

I am newer here but I didn't think 850/1600 could support 600whp. I'm sure Howard Coleman can and will chime in here with the supporting math but I would imagine you would be at the limits of that fuel setup at best. Just my 2c

 

it's fine people have pushed 400rwhp on 550 and 850 not that i would

 

lol honestly i dont know how that works, this is all new to me too.
but if rotary performance built it i trust them, i even called them to verify, everything

 

The guys at Rotary Performance are top notch fellows! They really know their **** and would not steer you wrong, or try to get you to buy something you don't need.

If you're working with them then you are in good, very capable, hands =)

completely agree... since they are most familiar w your setup i suggest you ask them.

i believe the "74" mm turbo you have is very similar to a GT4202. most of Compturbo's stuff is close to other brands.

if so, the GT4202 makes 95 pounds per minute of air (at 35 psi) which translates to 716 SAE rotary rwhp.

716 requires 6658 CC/Minute of gasoline at 11-1 AFR.

that assumes you run the injectors at max duty of 85% and you want enough fuel to tune to 10 to 1.

feel free to adjust any of the above assumptions.

once you get on the other side of 600 you need clearance rotors and a replacement for the stock thrubolts.

things get real different above 600 in every way.

600 is 690 flywheel divided by 159 cu inches it is 4.33 hp per cubic inch. i suggest you build a supply of shortblocks.

also, no matter what you run on the street w that turbo, you absolutely need water or water/meth or meth injection.
